(339 S. Erwindale Ave., Azusa, Calif.) Filed Feb. 10, 1961, Ser. No. 88,379 6 Claims. till. 16--105) This invention relates to an adjustable door hanger, particularly for sliding doors.

An object of the present invention is to provide an adjustable door hanger for sliding doors that automatically retains its adjusted position and, therefore, is not subject to maladjustment as may result from accidental loosening or tightening of clamping or locking screws or nuts.

Another object of the invention is to provide door hanger means that may be adjusted with easy facility by means of a single tool in :a one-handed operation, thereby enabling accurate adjustment q-uickly and easily.

This invention also has for its objects to provide such means that are positive in operation, convenient in use, easily installed in a working position and easily disconnected therefrom, economical of manufacture, relatively simple, and of general superiority and serviceability.

The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in the course of the following description and which is based on the accompanying drawing. However, said drawing merely shows, and the following description merely describes one embodiment of the present invention, which is given by way of illustration or example only.

In the drawing, like reference characters designate similar parts in the several views.

SFIG is a vertical sectional view through the framing of a sliding door showing a preferred embodiment of the present invention.

FIG. 2 is a longitudinal sectional view as taken on the line 2 2 of FIG. l.

FIG. 3 is a similar view with the present door hanger in another adjusted position.

FIG. 4 is an enlarged cross-sectional view taken through the adjustment portion of the present hanger.

FIG. 5 is a similarly enlarged longitudinal sectional View of a pivot construction for the adjustable member of the hanger.

In quite the usual way a track llt)` is horizontally disposed and housed within a bottom-open enclosure 11 that, ordinarily, is embodied in ia partition, ceiling, or other portion of a building. A sliding door 12 is shown as disposed beneath said enclosure to close or open a space,

as the case may be, between the stiles 13 at opposite ends of the enclosure 11. The present hanger 14 represents one of two similar hangers that suspend the door 12 from the track so that said door may be slid longitudinally in the mentioned space between stiles 13 with the lower edge of said door suitably clear ofthe iloor or licor-covering to insure against arresting of the door movement during such sliding thereof.

The present hanger 14 comprises, generally, a bracket 15 adapted to be afxed to the door, preferably the top edge thereof, `an arm 16 adjustably carried by said bracket md mounting a roller 17 at one end thereof that is engaged with the track 10' to roll therealong, means 1S to pivotally frictionally connect said arm 16 to the bracket 15, and self-locking means 19 to automatically adjust and retain the adjustment 'of the opposite end of the arm '16 to, thereby, adjust the spacing above the door top of the roller 17, thus, adjusting the position of the lower edgeV of the door relative to the lioor or covering thereon.

The bracket 15 comprises an angle member having one leg thereof 20 affixed to the top edge of door .12 and the other leg 21 vertically disposed. Said leg v21 is shown 3', E Patented Aug. 13, 1 963 ice p arm '16 that has the roller 17 has an enlarged circular opening .25 therein and, between said opening and the roller l17, a small hole 26 is provided.

The roller -17 is preferably of the anti-friction type and is advantageously made of nylon or other suitable longwearing plastic material. `In this case, said roller extends laterally from arm 16 so as to be disposed over the leg 2li of the bracket 15.

The pivot means 18 is shown as a stud or rivet 27 that extends through slot 241and hole 26, with a head 28 there-` on bearing against the outer face of bracket leg 21 and the end 29 opposite said head swaged over a washer 30 that is disposed against the outer face of arm 16. The pivot 18 is made to be frictionally tight, yet enabling the arm to move around the axis of rivet l27 and said rivet to movel along the slot 24. A

The self-locking arm-adjusting means llit is shown as a stud 31 that extends through hole 22 in the bracket leg 21 and provided with a polygonal orl similar head 32 that resides on the outer side of said bracket leg 21, a compression washer 33 between said leg 21 and the head 312, and an eccentric circular disc 34 connected, as by staking, to the stud 31 and of a diametral size to t in the circular opening `25 in the arm 16.

It will be clear that a tool applied to head 32 to turn the same will turn said eccentric disc on the axis of stud 31 and, because of the friction imposed by the compression washer 33, said disc will remain in the rotated position of adjustment until moved by turning of the stud head. It will be clear that turning of the eccentric disc 34 causes the arm V16 to move around its pivot as before described, thereby causing the roller 17 to have a position relative to the top edge of the door 12 that varies according to the adjusted rotational position of the disc 32. It will also be clear that the friction provided at both means 18 and 19 will hold the adjustment. FIGS. 2 and 3 show that the door may be raised or lowered as desired to achieve the bottom-edge clearance from the floor or a covering thereon as needed for smooth sliding operation of the door along the track 10.

The slot 24 is shown as sloping downward from the cam end of the bracket. This slope enables maximum adjustment of the arm .16, since the high adjustment, as in FIG. `2, has the nivet 27 in the high end of the slot and low adjustment, as in FIG. 3, has the rivet in the 10W end of said slot.

While the foregoing has illustrated and described what is now contemplated to be the best mode of carrying out the invention, the construction is, of course, subject to modification without departing from the spirit and scope of the invention. Therefore, it is not desired to restrict the invention to the particular form of construction illustrated and described, but to cover tall modifications that may fall within the scope of the appended claims.

Having thus described this invention, what is claimed and desired to be secured by Letters `Patent is:

1. An adjustable door hanger comprising a bracket adapted to be aiiixed to a sliding door, an arm, a friction pivot connecting an intermediate point of said arm to the bracket, said pivot embodying a slot therein whereby the arm is adapted to move longitudinally during pivotal movement thereof with respect to said bracket, a roller carried by one end of said arm and adapted to be mounted to support the door for sliding movement, and eccentric cam means adjustably carried by the bracket and engaged with the other end of the arm to move the latter around its pivot to, thereby, adjust the spaced relationship of the door and the rollerV by movement of said friction pivot in said slot in response to adjustment of said eccentric cam.
